• Vented design to improve cooling and reduce brake fade
• Rust-resistant coating to extend rotor life and maintain appearance
• Nominal thickness of 1.27 inches (32.2 mm) with discard thickness at 1.18 inches (30 mm)
• Overall height of 2.01 inches (51 mm) and outside diameter of 11.65 inches (296 mm)
• Five mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter
• Non-directional brake surface suitable for conventional braking systems

Technical Details and Construction

The DuraGo BR900544-01 rotor features a full cast iron construction, providing a solid and durable braking surface designed to withstand the thermal stresses of daily driving. Its vented design allows air to flow between the rotor faces, enhancing heat dissipation and reducing the risk of brake fade during extended use. The rotor includes a rust-resistant coating that helps prevent corrosion, maintaining rotor integrity and appearance over time.

With a nominal thickness of 1.27 inches (32.2 mm) and a discard thickness of 1.18 inches (30 mm), this rotor meets OEM specifications for thickness and wear limits. The overall height measures 2.01 inches (51 mm), and the outside diameter is 11.65 inches (296 mm), ensuring proper fitment and compatibility with the braking system of Lexus GS300 and IS250 vehicles. The rotor mounts with five bolts on a 4.5 inch (114.3 mm) bolt circle diameter, with each mounting hole measuring 0.57 inches (14.5 mm) in diameter.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is specifically designed for use on the following Lexus models:

• Lexus GS300
• Lexus IS250

It is intended for drivers seeking a direct replacement rotor that meets factory specifications for fit, form, and function. The rotor is suitable for conventional braking systems without ABS tone rings and features a non-directional braking surface, making it compatible with standard brake pads.

Common Issues Addressed by This Rotor

• Brake pulsation or vibration caused by warped rotors
• Reduced braking efficiency due to worn or thin rotors
• Corrosion and rust buildup affecting rotor performance
• Overheating and brake fade during extended braking
• Noise and uneven pad wear from damaged rotor surfaces

Installation Notes and Tips

When installing the DuraGo BR900544-01 rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify that the rotor thickness is within the specified nominal and discard limits to maintain safe braking performance. Use proper torque specifications for the mounting bolts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure optimal braking efficiency and rotor longevity.
